Setting battery charging maximum value of temperature. If battery temperture is over than 45 degree, set charge current to 0 mA, and charge state to idle. Then LED will turn to white in idle state. BUG=chrome-os-partner:49695 BRANCH=glados TEST=check the battery will not charge when battery temperture is over than 45 degree, and LED turn to white. Then temperture is less than 45 degree, the battery will charge and LED turn to amber.
